Glenn Quagmire, who mostly goes by his last name, is one of the Griffins' neighbors on Family Guy.  Quagmire is a bit of a lovable perv and is voiced by the show's creator, Seth McFarlane.

Though you could never tell by the way he acts, Glenn is actually an airline pilot.  Oh and Quagmire has a huge thing for Lois and ruined Cleveland's marriage.  I say don't leave him alone with your daughter or wife.

Cleveland: Hey Quagmire, how was your date last night?
Quagmire: Cleveland, it was amazing. You know what I discovered last night? Women have a fourth hole.
Joe: What?
Quagmire: Yeah, I mean it's only visible if you're looking from exactly the right angle, like the entrance to Hogwarts. But ya gotta believe that it's there.
Peter: Man, I envy you single guys. No families, partying whenever you want. These are the only people I get to party with. (holds out his wallet, with a picture of the kids)
Quagmire: (Pointing to Meg) Oh, that's where the fourth hole is, right there. Right there in the back of the knee.
